Description
The Leviton N1303-DS Powerswitch® Industrial Grade AC Manual Motor Controller provides safe, reliable manual ON/OFF switching control and disconnect capabilities for heavy-duty motor loads. Housed in a durable NEMA Type 1 gray steel enclosure, this 30 Amp, 600 VAC double-pole (2-pole) manual motor controller is engineered specifically for single-phase commercial and industrial motor applications, and is fully certified for use as a local motor disconnect.
Built to withstand demanding manufacturing environments, the N1303-DS features flame-retardant (UL 94 V-0) thermoplastic polyester construction and heavy-duty silver-cadmium contacts that deliver exceptional arc resistance over a 6,000-cycle inductive motor load lifecycle. Equipped with back and side wiring connections for #10 to #8 AWG wire and clearly marked terminals (L1, L2, T1, T2), this enclosed switch is ideal for controlling conveyor systems, industrial pumps, HVAC equipment, and air compressors.
